James Cameron to Travel Solo to the Ocean's Deepest Point

In the coming weeks, Cameron plans to do something no one has ever done before -- travel alone to reach the furthest depths of the ocean to the bottom the Mariana Trench, some six miles beneath the waves. There, at the deepest point on the Earth's surface, remains one of the least understood places on the planet, an alien region quite possibly home to lifeforms never before observed by science.
